AD/BELL 206/58 Full Cell Cavity and Vent Line Modification 11/2008

Requirement:	CANCELLED.
This AD is cancelled on 23 October 2008.
Background:	This unique Australian AD, issued in 1974, required modification of the fuel cell cavity and vent line in accordance with Bell Alert Service Bulletins 206-10-74-1 and 206-10-74-2 to prevent false fuel quantity indication at high airspeeds.  The AD compliance was within 100 hours time in service after 31 May 1974.  As all aircraft would have been modified by now, the AD is no longer required.
